The technology of Helium purification recycle plant
Wednesday, 14 November 2018
The common method of helium purification recycle plant is cryogenic and condensation. In addition, a lot of new technologies in the cryogenic field are also adopted in the plant development process, including vibration reduction of high pressure helium compressor, special welding technology of cryogenic and high-pressure copper pipelines, and cryogenic and high pressure flexible sealing technology, etc., to optimize products. On this basis, making a breakthrough in the purification technology through membrane separation method. A low-purity helium with a purity of 10% or more was purified to more than 99.5% and the recovery rate of system purification was more than 60%. Features of technology A new type of recycling plant for waste helium purification manufactured by Chinese enterprises monitoring the
Scope of application-helium
Wednesday, 07 November 2018
Helium is mainly used for the detection of leakage in medical and military refrigeration semiconductor pipelines, high-precision welding metal, manufacturing deep-sea diving photoelectronics, production of balloon borne scientific research and military, etc. 1.Nuclear magnetic resonance (cryogenic superconductivity) field Magnetic resonance imaging (MRI) uses the cryogenic superconducting magnet technology requires cooling liquid helium, according to the statistics, nuclear magnetic resonance (NMR) imaging accounted for 34% of the world’s dosage of helium, one of the biggest end use industry. Although demand for magnetic resonance imaging in developed countries is declining, but demand is still strong growth in developing countries, so as to keep the strong demand of liquid helium. 2.Refrigeration (home appliances) field Helium gas is mainly used for detecting the leakage
What does distillation mean?

For two substances of different boiling point (such as oxygen and nitrogen) compositing mixed solution, while after absorbing heat and partial evaporation, volatile composition nitrogen will evaporate more. Mixed steam releases heat and part of it condensates, while composition oxygen which is difficult to volatilize will condensate more. If you make saturated steam with higher temperature and saturated solution mixed, then steam gives off heat to saturated solution. After releasing heat, part of steam will condensate. Solution will absorb heat and part of it will evaporate. When partial steam’s condensation happens, due to oxygen condensates more, so the concentration of lower boiling point composition (nitrogen) in steam would be promoted. During partial evaporation of solution, owing to nitrogen evaporates more, the concentration of higher boiling point composition (oxygen) will be promoted. If after partial evaporation and partial condensation

Membrane air separation of nitrogen
Friday, 20 July 2018
Membrane air separation of nitrogen called hollow fiber membrane separation, It is made of air, which can separate oxygen and nitrogen under certain pressure by using different gases such as oxygen and nitrogen to have different infiltration rates in the membrane. Compared with other nitrogen plant it is more simple structure, smaller volume, no switch valve, less maintenance, produce gas quickly (≤3 minutess), convenient of capacity, it is especially suitable for medium and small of the nitrogen purity to 99.5% or less nitrogen users, have an optimal function price. When the purity of nitrogen is over 98%, the price is more than 15% higher than that of PSA nitrogen generator of the same specification.
Deep freezing technology
Saturday, 14 July 2018
Deep freezing technology is the most widely used air separation technology at present, and it is also the focus of competition among countries in air separation technology. Cryogenic technology uses the principle of different boiling points of oxygen and nitrogen gases under the same pressure to separate gases Compared with the separation device of other processes, the air separation device developed by cryogenic technology can easily meet the requirements of high yield and high purity, which can meet the requirements of modern large-scale industrial production. Therefore, the most discussed and widely used in the air separation industry is the air separation device using cryogenic technology.
